The strip samples were cast using a high solidification cooling rate vacuum sampling method to simulate the solidification conditions of the industrial twin roll thin strip casting (TRSC) process. As-cast sampl...

Modern Electric Arc Furnaces (EAF) employ ultra-high-power electrical input to minimize the scrap melting time. Increasing the operating voltage increases arc length and enhances the active power, but radiation energy losses also increase if the arc is exposed to the furnace, resulting in a drop in thermal efficiency and causing hot spots in the fu...

Continuously cast near net shape blanks have been widely used in industry owing to the benefit of producing items close to final shape. However, for complicated shaped blanks, such as I and H beams, using near net shape blanks is not enough to prevent unwanted mass flow and deformation during hot rolling. The strength of the rolled material, pre-ex...

Spherical cavity expansion is a well-known theory used to develop penetration models and failure analysis on solids. However, some limitations of this theory have been found, especially when complex materials have been tried to model. In this paper, steady cavitation assumptions are studied for strain-rate-sensitive solids, in order to apply cavity...

The addition of steel waste in the form of slags and dust to cement is beneficial to the environment because waste can be immobilized, and thus, decreasing the waters contamination. In this paper, paste and mortar-based Portland cement samples with up to 70.0 wt% of steel dust were investigated. Since it is known that for one ton of Portland cement...
